Recipients Validation fails if there is a dash in the name.

I try to send an email to people who have a dash in their name. (Happens for example sometimes with double names in German. e.g. Hans-Peter)

message = MessageSchema(
    recipients=my_email_str,
    [...]
)

This input works: my_email_str = "Hans Peter Example <hans-peter@example.com>"

This input fails: my_email_str = "Hans-Peter Example <hans-peter@example.com>" with

pydantic.error_wrappers.ValidationError: 1 validation error for MessageSchema
recipients -> 0
  value is not a valid email address (type=value_error.email)

Having a closer look at the fastapi-mail code, i see that it's actually not supposed to handle
pydantics NameEmail schema (e.g. Example Name \example@example.com\) but pydantics EmailStr schema (e.g. example@example.com).

So, I'm even a bit surprised that the first input actually works. Depending how you look at it, this is now a bug report or a feature request :)
